SWING OR I-IAMMOCK HANGER.

Application filed May 14, 1921.

To all whom it may concern Be it known that I, WILLSON TAYLOR, a citizenof the United "States, residing at niontown, in the county of Fayetteand State of Pennsylvania, have invented a new and useful Swmg orHammock Hanger, of which the following is a specification.

his invention relates porting swings, hammocks, or for other purposes.

The object is to provide a hanger for the support of swings, hammocks,cots or other similar movable devices to permit of the backward andforward travel of the same, while under relatively heavy load, Withoutthe usual creaking or grinding sounds accompanying the ordinary hanger.

Another object is to provide a hanger having anti-friction means locatedin the swing ing hanger in such position as to ride at all times on thestationary hook or ring secured to the ceiling or other support, and topermit of the swinging action of the swing supporting chains or ropes.with a minimum amount of friction and without noise, and reducing thewear of the contacting points of the said hook and hanger and prolongingthe life of the same.

A further object is to provide an anti-friction device of this characterhaving the foregoing advantages which comprises a minimum number ofparts, thus permitting of its manufacture and sale at a low costand soconstructed as to permit of hanging the swing, cot or hammock supportedthereby in the simple manner of an ordinary swing.

A full and complete understanding of the invention may be obtained froma consideration of the following detailed description, taken inconnection with the accompanying drawing forming a part of thisspecification, it being understood that while the drawing shows apractical form of the invention, the latter is not to be confined tostrict conformity therewith, but may be changed or modified, so long assuch changes or modifications mark no material departure from thesalient features of the invention as specifically pointed out in theappended claims.

In the drawing, in which similar reference characters designatecorresponding parts several figures:

to hangers for sup- Patented Aug. 30, 1921. Serial No. 469,527.

Fig. 2 is a front elevation, partly in section, of the same.

Fig. 3 is an enlarged detail sectional view of the manner of mountingthe anti-friction balls in the hanger.

Fi 4 is a detail elevation of the ball socket.

An ordinary hook I having its shank formed into a lag screw 2 is screwedinto the ceiling 3 or other support, and it will of course be understoodthat the same may consist of an eye bolt or a stout loop or staplecarried by an attaching plate screwed in position.

The ball-bearing hanger which constitutes my invention is composed of alength of stoutrod iron bent into a substantially diamond shapepreferably, comprising the terminal V-shaped hooks 6 and 7 respectively,the lower hook 6 having its crotch 8 somewhat rounded to provide arelatively wide seat for the reception of one of the links of thesupporting chain 9 or the looped end of a rope, as the case may be, inorder to provide for the independentswinging action ofcthe chain orrope, with relation to the hanger 4. This independent action, however,is very slight when the hammock or swing is under a heavy load, as thelatter causes the chains or ropes and the hook memhere to movesubstantially in unison, in a direction at right angles to the plane ofthe ceiling hooks l.

The upper hook 7, which is in the form of an inverted V, is ofsubstantially the same width at the mouth thereof, as is the lower hook,and the terminals 10 of the rod comprising the hanger are arranged invertical alinement and in spaced relation to each other to provide anentrance throat of sufficient width to readily permit the introductionof the upper hook 7' into the ceiling hook 1, as will be readilyunderstood.

While a substantially diamond shaped hanger has been shown anddescribed, it will be seen that the same may partake of an S- shape, inwhich event the links of the supporting chains or the loops of the ropeswill be engaged with the lower hooks of the movable hangers from theopposite direction, the lower terminal 10 then being on the oppositeside. Indeed it is not necessary that duplicate hooks be provided, butin place of the hook 6, that end of the hanger may be formed with aring, as the real invention resides in the other end of the hanger.

In the opposed inner faces of the upper terminal and the upper portionof the connection between the hooks 6 and 7, there are provided opposedconcave seats 11 into which are located a pair of steel balls 12, Whichsnugly fit the same and are in contact with each other, the same restingon the hook 1, at one side of the vertical axis thereof and tree torotate in any direction While under strain without causing any noise andacting as a roller on the hook l to reduce the wear thereof to aminimum.

The seats 11 are ground smootnand are provided with a plurality ofradially disposed grooves 13, adapted to be filled with grea; graphiteor other lubricant to fur ther enhance the frictionless and noiselessfeatures of the device.

()ne way of making the device is as follows: The sockets or seats arefirst drilled in the piece of rod iron. at the proper points beforebending the same. The lower bend forming the hook (3 is first made. Thenthe iron is heated at the point where the bend tor the upper hook is tobe formed, taking care that the metal at the sockets or seats is keptcool. When the proper heat has been obtained for the bending of theiron, the hanger is laid on a flat surface and the balls also laidthereon and then the upper hook is squeezed around them, causing them tofit into their proper sockets or seats; it heing understood that theballs are retained in their seats wholly by the bending of the hook. The space separating the sides of said hook is less than the combineddiameter of the balls. From the foregoing it will be seen that a simplehanger for swings, hammocks or cots has been provided which may beeasily inaini'tactured and sold at a low cost, the same comprising onlya single piece of rod iron, especially bent and formed into shape andtwo balls, all of which may be readily found upon the market, and thatthe same may be easily and quickly attached to any swinging devicewithout the necessity for any-additional hooks and regardless of thesize of the ceiling hooks already in place.

N hat is claimed is:-

l. A ball bearing hanger comprising a member having a hook at one end,the arms of said hook having on the inner side opposed concave seats anda pair of balls mounted partially Within said seats and projectingtherefrom and contacting with each other.

2. A ball bearing hanger comprising a member having a hook at one end,the arms of said hook having on the inner side opposed concave scats,said seats being provir ed with radial grooves to contain a lubricant,and a pair oi bads mounted partially Within said seats and projectingtherefrom and contacting with each other.

3. A ball-bearing hanger comprising a double-ended hook formed of asingle length of rod iron, one oi": the hooks having in its oppositearms a pair of opposed seats spaced from the crotch of the said hook,and a steel ball fitting partially within each seat and adapted to heareach against the other.

4.. A ball bearing hanger comprising a member having a hook-shaped end,a pair of balls contacting with eaen other at a point short of said end,and seats provided in said hook-shaped end to receive said balls, thespace separating the sides of said end being less than the combineddiameter of said balls so as to hold the balls in said seats.

In testimony that I claim the foregoing as my own, I have hereto ailixedmy signature.

YVILLSON BERNARD TAYLOR.
